Charging the power supply unit

All power supply units with an integrated and rechargeable energy store are delivered with a maximum charge of 30% in accordance with applicable transport regulations. If you use an external charging voltage (V IN) during operation, the power supply unit is constantly charged by the charge controller integrated in the 4-Channel Data Logger .

If no external charging voltage (V IN) is available during operation, the power supply unit must be fully charged before initial use.

For instructions on removing the rechargeable battery, see Replacing the power supply unit.

Important: Only use the PSU Charger (300697) to charge the power supply units. The charger specifications must be observed. The use of other chargers can destroy the power supply unit, for example, causing the cells to leak or an explosion, etc.

Charger with power supply unit

1 Plug-in power supply (included in the scope of delivery of 300697) 4 PSU Charger (300697)
2 Button (reserved for extension) 5 Status LED of the PSU Charger

Possible states of the status LED:

off: no PSU inserted

Flashing green: PSU is being charged

Green: Charging completed

Flashing red 1x every 5 seconds: PSU does not contain a rechargeable energy store

Flashing red 2x every 5 seconds: PSU damaged

Flashing red 3x every 5 seconds: Supply voltage of the charger is too low

3 Power supply unit e.g. PSU413D+ AP (300524)

 

 

 

 

 

 

 

The charging process starts as soon as the power supply unit is inserted in the charger. If the status LED on the charger flashes red once every 5 seconds, the power supply unit inserted in the charger does not contain a rechargeable energy store. If the status LED flashes red three times every 5 seconds, the supply voltage of the charger is too low. In this case, check the cable connection between the plug-in power supply and the PSU Charger and check whether the plug-in power supply is correctly connected to an electric socket. If the status LED flashes green, a normal charging process is in progress. The charging process is complete when the status LED turns green.

If the status LED flashes red twice every 5 seconds, the power supply unit is faulty. Possible reasons for this include a broken cable, short circuit or defective cells. In this case, the used power supply unit must be replaced with a new one.

Tip: Rechargeable batteries are wear parts that lose capacity over time. The capacity is also reduced at high or low ambient temperatures and under intensive use.
Note: Ensure that power supply units, especially ones with integrated energy store (rechargeable battery or battery), are disposed of in line with environmental requirements. Power supply units with depleted rechargeable battery or battery can be returned to the manufacturer or handed in at suitable collection points.
